Understanding and estimating vegetation mass and productivity in recent years has become increasingly important, especially with advancements in environmental economic valuation.
Terra’s data is used in a range of activities relating to vegetation mapping including:
- Urban Planning
- Corridor Assessment
- Environmental Monitoring
Urban planners have realized the vital role vegetation plays in reducing ambient temperature, moisture and pollutant capture, energy use and subsequent ground level ozone reduction. Vegetation mapping through the use of advanced remote sensing technology enables researchers to quantify and qualify the amount and health of vegetation within urban centers. Growth models, climate change scenarios and detailed valuation studies can be carried out, allowing for accurate day-to day management and future planning. Terra’s LiDAR and hyperspectral data have been used successfully to identify individual trees that were infected with Emerald Ash Borer Beetles. This study was a feature story in the PE&RS magazine in 2009. ASPRS August 2009.
LiDAR and hyperspectral fusion provides an unmatched depth of data used for a range of activities including climate change adaptation planning, vegetation species identification, vegetation health assessments and enhanced forest inventories (EFI). Terra provides regular services to public and private sector organizations that rely on high-resolution and comprehensive vegetation mapping services.
Recently, using high-resolution hyperspectral imagery provided by Terra, researchers at the University of Victoria made breakthroughs in being able to identify forest stands under ‘green attack’ by the mountain pine beetle. Having the ability to detect tree stands affected by the mountain pine beetle years before tree mortality occurs is the first step towards stemming the tide of extensive damage in conifer forests caused by recent outbreaks of the mountain pine beetle. Vegetation mapping plays a key role in climate change adaptation strategies.
